Add JDK11 support without enabling in CI (#31644)

* Upgrade bouncycastle

Required to fix
`bcprov-jdk15on-1.55.jar; invalid manifest format `
on jdk 11

* Downgrade bouncycastle to avoid invalid manifest

* Add checksum for new jars

* Update tika permissions for jdk 11

* Mute test failing on jdk 11

* Add JDK11 to CI

* Thread#stop(Throwable) was removed

http://mail.openjdk.java.net/pipermail/core-libs-dev/2018-June/053536.html

* Disable failing tests #31456

* Temprorarily disable doc tests

To see if there are other failures on JDK11

* Only blacklist specific doc tests

* Disable only failing tests in ingest attachment plugin

* Mute failing HDFS tests #31498

* Mute failing lang-painless tests #31500

* Fix backwards compatability builds

Fix JAVA version to 10 for ES 6.3

* Add 6.x to bwx -> java10

* Prefix out and err from buildBwcVersion for readability

```

* Also set RUNTIME_JAVA_HOME for bwcBuild

So that we can make sure it's not too new for the build to understand.

* Align bouncycastle dependency

* fix painles array tets

closes #31500

* Update jar checksums

* Keep 8/10 runtime/compile untill consensus builds on 11

* Only skip failing tests if running on Java 11

* Failures are dependent of compile java version not runtime

* Condition doc test exceptions on compiler java version as well

* Disable hdfs tests based on runtime java

* Set runtime java to minimum supported for bwc

* PR review

* Add comment with ticket for forbidden apis
